feat: runner-aware tools

Set up an IPC channel between vite-task and the processes it spawns,
so the spawned tools can declare at runtime what they actually read,
wrote, or cared about, and vite-task uses that to decide what to
fingerprint in the cache.

Squashes the PR's commit history onto current `origin/main` after
the previous merge history (multiple merges with main as it evolved)
made a true commit-by-commit rebase impractical (heavy conflicts on
older commits like `30a97a2e` against main's parallel evolution of
the same fixtures).

 - **Added** `output` field for cached tasks: archives matching files after a successful run and restores them on cache hit ([#375](https://github.com/voidzero-dev/vite-task/pull/375))
 - **Fixed** Windows cached tasks can now run package shims rewritten through PowerShell; default env passthrough now preserves `PATHEXT` ([#366](https://github.com/voidzero-dev/vite-task/pull/366))
 - **Added** Platform support for targets without `input` auto-inference (e.g. Android). Tasks still run; those relying on auto-inference run uncached, with the summary noting that `input` must be configured manually to enable caching ([#352](https://github.com/voidzero-dev/vite-task/pull/352))
+- **Added** `output` field for cached tasks: archives output files after a successful run and restores them on cache hit. Defaults to automatically tracking files the task writes; accepts globs (e.g. `"dist/**"`), `{ "auto": true }`, and negative patterns (`"!dist/cache/**"`) ([#321](https://github.com/voidzero-dev/vite-task/pull/321))
 - **Fixed** `vp run` no longer aborts with `failed to prepare the command for injection: Invalid argument` when the user environment already has `LD_PRELOAD` (Linux) or `DYLD_INSERT_LIBRARIES` (macOS) set. The tracer shim is now appended to any existing value and placed last, so user preloads keep their symbol-interposition precedence ([#340](https://github.com/voidzero-dev/vite-task/issues/340))
 - **Changed** Arguments passed after a task name (e.g. `vp run test some-filter`) are now forwarded only to that task. Tasks pulled in via `dependsOn` no longer receive them ([#324](https://github.com/voidzero-dev/vite-task/issues/324))
 - **Fixed** Windows file access tracking no longer panics when a task touches malformed paths that cannot be represented as workspace-relative inputs ([#330](https://github.com/voidzero-dev/vite-task/pull/330))

+## New Crates and Packages

+When creating a new Rust crate or npm package, add a concise `README.md` stating its goal in one or two sentences. Do not include implementation details, API docs, or links to other docs — those belong in source comments or the design docs.

 ## Changelog
 
 When a change is user-facing (new feature, changed behavior, bug fix, removal, or perf improvement), run `/update-changelog` to add an entry to `CHANGELOG.md`. Do not add entries for internal refactors, CI, dep bumps, test fixes, or docs changes.
